Can members of provincial calligraphy associations be useful in promotion?

I don’t know what promotion you are talking about? Calligraphy itself or other jobs? My understanding and answer is that provincial calligraphy association members are definitely useful in promoting themselves to national calligraphy association membership. Because according to the "Chinese Calligraphers Association Charter", members of the Chinese Calligraphers Association, if they meet the basic conditions, must be recommended by their local (provincial-level municipality-level) group member unit and submit materials before they can join the association. The Chinese Calligraphers Association does not directly and actively recruit members. Anyone who directly and actively recruits you to join the membership without going through the recommendation of local group membership units or submitting materials is false. This official website has stated. Joining the Chinese Calligraphers Association is a certification of your calligraphy level by a national professional authority. It also marks that your calligraphy level has reached a new level and entered a new stage.
